Google App Engine Go SDK:请求' /'失败

我刚刚开始使用GAE,我在这里有https://developers.google.com/appengine/docs/go/gettingstarted/devenvironment的指南和一些你好的单词教程https://developers.google.com/appengine/docs/go/gettingstarted/helloworld

我的问题是当我输入goapp serve时,它有效。并显示如下日志:

INFO     2014-05-18 08:44:57,130 devappserver2.py:765] Skipping SDK update check.
WARNING  2014-05-18 08:44:57,135 api_server.py:374] Could not initialize images API; you are likely missing the Python "PIL" module.

INFO     2014-05-18 08:44:57,156 admin_server.py:117] Starting admin server at: http://localhost:8000

但是,当我试图访问http://localhost:8080时,它并没有告诉我“你好,世界!”在浏览器中。和错误日志显示我这样:

ERROR    2014-05-18 08:48:05,002 module.py:714] Request to '/' failed

我已经谷歌了,并在这里尝试另一个入门教程http://blog.joshsoftware.com/2014/03/12/learn-to-build-and-deploy-simple-go-web-apps-part-one/ 但它也不起作用。

我该怎么办?

  • 我在ubuntu 12.04,Python 2.7.3,go go version2.1.1 linux / 386
  • 使用go_appengine_sdk_linux_386-1.9.4.zip

这是我的hello.go和app.yaml

hello.go

package hello

import (
   "fmt"
   "net/http"
)

func init() {
   http.HandleFunc("/", handler)
}

func handler(w http.ResponseWriter, r *http.Request) {
   fmt.Fprint(w, "Hello,")
}

的app.yaml

application: helloworld
version: 1
runtime: go
api_version: go1

handlers:
- url: /.*
  script: _go_app

谢谢,

不确定这是否会对任何人有所帮助,但我遇到了完全相同的问题,最后将其追踪到我的主机文件中。基本上发生的事情是app引擎服务器运行在0.0.0.0:8080但接口/输出显示localhost:8080。在我的hosts文件中,0.0.0.0:8080未映射到localhost所以:

  1. 使用vim或其他
  2. 编辑您的/private/etc/hosts文件
  3. 0.0.0.0 localhost添加到您的主机文件
  4. 保存,启动新终端并尝试再次运行appengine服务器
  5. 在那个简单的编辑之后,一切都适合我。
